This is a very small representation of the Zakaal. Its probably shorter than the palm of your hand.
HOWEVER: all of the details shown on the anime are there. The cockpit even opens (there is an unpainted pilot inside, this was a nice surprise as given the size, I was not expecting an opening-head-cockpit). High grade articulation in all limbs and a good lucking gold color is used.
The Zakaal is not a popular mecha in toy or model kit form. I was definitely expecting a lot less, so this is a great item for the size. I recommend it.
